Thanks for the query,
can be detected by a blood test
as early as 11 days after conception .
And about 12 - 14 days after conception by a urine test.
In general the hCG levels will double every 72 hours.
The level will reach its peak in the first 8 - 11 weeks of pregnancy
and then will decline and level off for the remainder of the pregnancy.
Since you have started to ovulate there are chances that you could be pregnant.
Get your urine pregnancy test done.
If it is positive, consult your doctor for further course.
